i first heard many tunes off the soul supply lp's and then went on to try and get the originals,but there were dissapointments, for example,i used to love the tune 'soul inc-what goes up must come down' on emblem,i eventually got the 45 just to be dissapointed,because there are 2 45 variations,the yellow copy is a live version and much slower,to which back in the late 80's just wouldnt have done me at all! the version on the lp is upbeat and a studio version, and as it turns out, extremely rare and hard to find.
both youtube variations here.
